[Elecraft] KX2 latest beta FW? (and spkr issue)

[Steve Sergeant]

I haven't seen much (if any) discussion about the latest KX2 beta
firmware (MCU 2.77 / DSP 1.50, May 26, 2017).

I generally don't try beta firmware unless I have a surplus device to
try it on (or unless I really don't care if device I'm trying on works).

Who else, outside of Elecraft employees, is running it? Have you noticed
any stability issues?

As a side note, I thought I had somehow blown my KX2 speaker by
accidentally turning off the AGC. So I just switched to earbuds and
didn't mess with it for a month. Then I got brave and set out to remove
the speaker from the KX2 bottom plate.

After removing the bottom plate from the KX2, and before removing the
speaker, I saw something shiny between the grille and the cone. It was a
single whisker-strand from the 26ga copper-clad I use for my portable
wire antenna. It was completing a magnetic circuit between the voicecoil
spool and the chassis sheet metal. After some very patient work with
tweezers, it was removed and my speaker was fixed.

I recommend that Elecraft glue a layer of fine mesh fabric to the inside
of the sheet metal to protect the speaker from this kind of dirt.
